Great service - 4 days delivery to Australia.
Really good instructions but I did come across one hiccup.
Mine was originally an AC car and the kit appears to be for non AC cars.
I had to make up a blanking plate to reduce the size of the original fan motor hole to be able to mount the unit.
Anyway,it all ended up good.
Can't tell you how good it is since the car isn't finished yet but their technician assures me their units are the best on the market even though he concedes their name isn't as big as their main competitor.
I assume he was referring to Vintage Air.
I also bought one of their billet slide controls.- Beautiful piece.
